Etymology: Hydrolab is a compound of "hydro-", from Greek "hydor" meaning water, and "lab", short for laboratory. It names a type of underwater research station, and the word is a modern technical coinage rather than an old one, so its history is simply the combination of those two parts. The most useful fact about the word is its original referent: the name belongs to a specific family of habitats built for scientists to live and work beneath the sea. Because it was coined for a particular kind of structure, the term describes the habitat itself and not the broader idea of a water-based laboratory.

Synonyms: hydrographic laboratory, water lab, aquatic research lab
